Audiophiles here are my component items. I have been pounding my head crazy for the best set-up to my DVD, receiver and TV. Any help you can provide would be greatly appreciated..

Onkyo TX-DS656 receiver:
Dolby Digital Processor
5.1 Channel External Outputs to connect a 5.1 channel decoder for DTS
Pioneer Elite DV-47A :
Dolby Digital/DTS decoder

I am lost on connections and cables to purchase....newbie I am...

sincerely,
Stavan
